two way and three-way switch locations

I installed 2 way switches at both end of our hallways, top and bottom of stairs and on either side of the master bed

best way to identify where you need to install 2 way switches is to walk through your floor plan and visualise how and where you want to turn on and off your lights. Consider your movements when you enter/leave the home, also turning off lights when going to bed and also think about middle of the night trips to the bathroom etc.

hallway light switches outside each bedroom. Life saver.
